The truth comes out: Kim Zolciak reveals she was once a church-going brunette before finding fame as a platinum blonde on RHOA

Kim Zolciak came to fame as a blonde sex pot on The Real Housewives Of Atlanta.

But when growing up in Pensacola, Florida, the 39-year-old TV star was once a brunette who attended church every Sunday.

The Don't Be Tardy star shared from her old days as a more demure beauty on her Instagram account over the weekend.

The star does not look to happy though.

Her caption read: 'Me and my grandparents at Church. Had to go every Sunday. #Catholic.'

Mommy: In another photo at Christmas she wrote: 'My girls giving me their Christmas presents ❤️ @arianabiermann @briellebiermann made me all these adorable cards and they were so proud.'
